But the Congress never did that. You won't find an appropriations bill where Congress allocated $X to Harvard and $Y to Princeton, etc. In fact, it did the opposite. Under Title VI, it empowered the executive branch to withhold money based on civil rights violations. And regardless of your view on Presidential power vis-a-vis executive branch agencies, 42 USC 2000d-1 specifically subordinates federal agencies' rules, regulations, and orders pursuant to Title VI to the authority of the "President."
